Abstract: Abstract of the Disclosure A method and apparatus for scoring plastic tamper indicating closures to provide the tamper indicating band that is connected to the closure by bridges formed by scoring.  The scoring is achieved by successively moving a rotating closure past a stationary primary knife blade having an arcuate concave interrupted cutting edge to form the bridges and then past a secondary knife blade having an arcuate concave uninterrupted cutting edge to accurately dimension the bridges.  The method and apparatus provides for supporting each knife blade on a holder wherein the position of the blade can be set by setting the blade into a knife blade holder using a setting fixture remote from the apparatus, clamping the blade within the knife blade holder, transferring the knife holder to a machine mounting on the apparatus, then attaching the knife holder to the machine mounting without further adjustment, such that the arcuate knife blade is aligned with the center of the radius of the arc of each arcuate knife blade lies on a radial line from the curvature of the cutting edge to the center of the apparatus  Each knife blade holder is preferably mounted on a slide on the rotary apparatus such that the arcuate edge can be adjusted so that the concave arc is parallel to the path of travel of the mandrels and at the required depth from the successive scoring.

Abstract: COTTER PIN GUARD AND RETAINER                    RUDOLPH E. NADHERNY                         ABSTRACT          A device for guarding and retaining a cotter pin in place after insertion in a pin or bolt.  The device is formed from springy sheet material, preferably in the form of a spring steel stamping.  It has a washer portion with a central opening to fit over a pin or bolt and a shelf portion extending to one side.  The washer portion has one or more tabs or spurs which frictionally engage the shank of a pin or bolt so as to retain the washer in place thereon.  The shelf portion is joined to the washer portion by a step or shoulder.  At its outer end the shelf has a fence which extends from the floor of the shelf in the same direction as the step.  The step has an opening through which the shank of a cotter pin may be inserted en through the aperture in a pin or bolt.  The shelf may be flexed so the fence is out of the way when a cotter pin is inserted.  On release the shelf springs back in place and the fence is in position to engage the head of the cotter pin and prevent its removal.  The device can be used with pins or bolts which fit the central opening in the washer portion with little clearance or which are undersized with respect to the central opening.

Title: Self-release choker hook
Inventor: EWART JAMES M
IPC: A01G23/099
Filed: 1994-10-26
Abstract: A choker hook has a main body and a latch member rotatable relative to said main body. The latch member is biased by a spring thereby to form a pocket to hold the ferrule of a choker cable used in logging operations. The latch member has a toe piece which will contact the surface of a log when the choker hook is rotated by the choker cable relative to the log. The force between the toe piece and its attached latch member will tend to rotate the latch member relative to the main body when the effect of the force on the choker hook is such that the toe piece is brought into contact with the outside of the log. The ferrule pocket will open and the ferrule and attached cable will be released thereby releasing the log being transported without manual intervention at the point of log release.

Patent CA-2144828-A1 (CA)
Title: Polymeric binder
Inventor: TANG XUN
IPC: C04B35/634
Filed: 1995-03-16
Abstract: A polymeric binder for ceramic materials is provided. The polymeric binder has a temperature range for pyrolysis which is broader than that for polymeric binders conventionally used in ceramic materials. The broader pyrolysis range provides for gradual removal of the binder when a ceramic part containing the binder is heated. Gradual removal of the binder minimizes the formation of voids and cracking in the ceramic part. Voids or cracking can lead to defects in the part, and destruction of the part may occur during removal if a polymeric binder used in the part is rapidly decomposed into gases. Therefore the polymeric binder of the present invention provides for ceramic parts with fewer defects and less chance of destruction than occurs with polymeric binders conventionally used in ceramic parts.
